Movie
Description
Created exclusively for the 2015 film adaptation, Manpuku serves as Gamba's primary companion. This character fulfills narrative roles previously held by Bobo in earlier story versions.

Manpuku sports distinctive green fur, marking his visual presence within the group. His characterization highlights a gluttonous appetite and an easygoing nature, traits mirroring the original Bobo from the 1975 anime. His physiology grants him a sensitive sense of smell, practically employed by the group to locate food during their travels.

Manpuku joined Gamba's expedition alongside other harbor-gathered mice sailors. This decision followed an encounter with Chūta, an injured mouse seeking help against the Noroi Clan's invasion of Yumemishima Island. Manpuku participates in the collective defense of the island's inhabitants, integrating into the team confronting the antagonistic forces led by the white-furred weasel Noroi.

Within the group, Manpuku maintains a secondary yet consistent presence. While energetic and curious like Gamba, he demonstrates less initiative in leadership or combat strategy, typically following Gamba's lead during adventures. His primary role involves providing support through his sensory abilities and participating in group actions rather than independently driving pivotal plot developments.

His entire documented character history unfolds within the central narrative arc of the 2015 film, spanning his recruitment to the defense of Yumemishima. No further appearances or development exist in other seasons, films, OVAs, or spin-offs beyond this single cinematic portrayal.
